2 Claims.

This invention relates to means for cleaning out drain lines of variouskinds, such as septic tank drainage lines and the like. n

The object of the invention is to produce a drain line cleaner whichwill have sufficient Weight and be of such shape as to readily clear thecross tile openings in septic tank drainage lines and break up and fiushaway accumulated deposits tending to clog the line.

While of particular adaptability to septic tank drainage lines, thedevice can of course be used on any type of sewage or other disposallines.

A further object of the invention is to produce a device which willreadily pass around sharp bends in the disposal pipes, even those havingas high as a 45 bend, though primarily it is intended for use onstraight lines.

A further object of the invention is to provide a simple and inexpensivedevice, and yet one which will be exceedingly effective for the purposefor which it is designed.

These objects are accomplished by means of` such structure and relativearrangement of parts y as will fully appear by a perusal of thefollowing specification and claims.

In the drawings:

Fig. 1 is a side elevation of my improved cleaner, showing it asattached to a hose line.

Fig. 2 is a longitudinal section of the cleaner.

Fig. 3 shows a modified form of attachment for the cleaner from thatshown in Fig. 2.

Referring now more particularly to the characters of reference on thedrawings, the numeral I designates a plug which is made of relativelyheavy metal, and is of a slightly oval contour longitudinally thereof.At one end the plug I is provided with threads 2 for connection with ahose 3. The plug I from the threaded portion 2 to its outer end isprovided with a central orifice 4 which terminates at its outer end in athreaded portion 5 for the reception of either a solid bull point 6 or ascrew point 1, which may be interchangeably used with the plug I asconditions may necessitate. Towards the forward end the plug I isprovided with a series of circumferentially disposed orifices 8 whichcommunicate from the central orifice 4 and project in a forwarddirection towards the outer end of the plug.

When the device is to be used it is attached to the hose 3 and said hoseis projected into the drain line, with water under considerable forceiiowing through the hose, through the central orifice 4, and out theorifices 8. The weight and shape of the plug I is such that it willreadily force its way through accumulated material in the drain line,the initial point of entry being made either by the bull point 6 or bythe screw point 1, according to which is being used, and which latterare used interchangeably according to the material to be broken through.

The force of the water discharging ahead of the plug, the weight of theplug, and the pressure given to the plug by an alined push against thehose 3 will very adequately break through and dislodge accumulatedmaterial in the line and clean the same. The length of the plug is suchthat it will readily clear tile openings in septic tank drainage lines,or joints of any character in other lines, and the curving outer sidewalls of the plug are such that the same may be readily withdrawnthrough the line without striking or getting caught on any projectionstherein.

From the foregoing description it will be readily seen that there hasbeen produced such a device as substantially fulfills the objects of theinvention, as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.

Having thus described the invention, the following is claimed as new anduseful, and upon which Letters Patent are desired:

1. A drain line cleaning device comprising the combination of a flexiblewater hose, a plug connected to the outer end of the hose and providedwith a longitudinal bore in register with the bore of the hose, suchplug comprising a relatively short heavy body, the outer side surface ofthe body being smooth and uninterrupted over its entire area, a solidmaterial piercing element fixed to and projecting outwardly from theouter end of the body, such element throughout its length being ofmaterially lesser cross sectional diameter than the plug, the forwardpart of the body to the rear of the front end thereof being providedwith a series of forwardly directed circumferentially disposed dischargeorifices which are in register with the interior bore of such body.

2. A device as in claim l in which the body is of oval shape inlongitudinal cross section.
